Ascot regulars were stunned on Thursday after a drunken brawl broke out during Ladies' Day.

The fight was captured on camera, with around six men throwing punches and one even appearing to use a chair leg to strike a fellow racegoer.

No arrests were made after the scrap, which took place beside the Victorian bandstand beside a champagne bar. It is not known what started the fracas, although one witness said it may have been after one man was insulted by another.
